The first edge 354 of wall 352 is connected to a first edge 380 of a first flange 382. Flange 382 includes a second edge 384 that is connected to a flange 386. Flange 386 extends perpendicular to flange 282 and includes a lip 388. Edge 380 of wall 376 is connected to a flange 390. Flange 390 is perpendicular to wall 376 and is co-planar parallelism with flange 382. Flange 390 is connected to a flange 392 and flange 392 is connected to a lip 394. Flange 392 is perpendicular to flange 390 and is parallel to flange 386 and walls 352 and 376. Lip 394 is perpendicular to flange 392 and is in co-planar parallelism with lip 388. Both lips 388, 392 are in spaced parallelism with flanges 282, 390.

Corner stud 350 is basically like corner stud 349 shown by FIG. 10 except that in FIG. 10 the two portions of the stud 244 are perpendicular to each other and the stud 244 fits into tracks 240, 242 that are perpendicular to each other. In the embodiment of FIG. 15, the two portions of stud 350 are separated by an angle x that is larger than 90 degrees and smaller than 180 degrees. The corner is formed where true tracks meet at a line 400. Two straight track sections may be cut at an angle to form ends that meet at line 400. Or, a track fitting 420 may be used at the corner. Track fitting 420 has opposite ends 422, 424 which are adapted to a butt against the ends of straight sections of track (not shown) that extend away and opposite directions from corner fitting 420. The intersecting tracks or track fitting 420, whichever is used, includes flanges 426, 428, 430, 432 which extend perpendicular from a bottom web 434. The upper and lower ends of the stud 420 fit into the corner region of the upper and lower tracks. Wall 376 is closely adjacent flanges 426. Wall 370 is closely adjacent flanges 432. Wall 352 is closely adjacent flanges 428. Wall 358 is closely adjacent flanges 432. In this embodiment, the edges of the wallboard panels are preferably beveled and the wallboard panels meet each other at the corners. Specifically, one pair of wallboard members are positioned against walls 352, 358 are secured to them by sheet metal screws. Another pair of wall members are against walls 376, 370 and are secured to them by sheet metal screws.
